Born in Stockholm, Wik studied at the Carl Wilhelmson painting school in Stockholm before moving to London for a year to attend the Westminster School of Art in 1924. Subsequently he moved to Paris where he attended the Académie de la Grande Chaumière and later studied under André Lhote. Lhote had started as a Fauve but later established himself as a Cubist and his influence is clear in Wik’s painting. He travelled widely in Europe and the United States during the 1920s and 30s, exhibiting in Sweden regularly. He held regular solo exhibitions with the leading Swedish galleries in the second half of the twentieth century with a memorial exhibition being held at the Agardhsgalleriet in 1989.
His work is represented in the collections of the Swedish Museum of Modern Art, the Swedish National Museum, The Institut Tessin in Paris, the Swedish State Art Council, King Gustav VI Adolf and numerous provincial Swedish public collections.
